Got scammed by a small business

Ordered from this genuine seeming business and opted for a express delivery as I was going to travel soon. Her site used to say "3-4 days to deliver in the south" but she has recently changed that. I texted her when my parcel didn't reach on the 4th day and she started saying it will take 4 BUSINESS days and how it's getting delayed because of the farmers protest etc and will come by the next day. While I can understand the whole "business days" thing she should really explicitly mention that on her site instead of just saying "3-4 days" it's quite misleading tbh. On the 5th day (the day I was travelling) it was still showing the package to be in Haryana (i live in Karnataka) and that's when I really lost it and politely asked her for a refund on my express fees (which is 150 rupees. ik that might seem like much for most people but it's a lot for a teenager like me who gets fixed pocket money). I feel asking for a refund was fair considering she didn't complete the delivery in the claimed time frame. Some more days passed and the package was finally delivered after A WHOLE WEEK (AFTER I got back from the trip I wanted the top for). Once again I asked her for a refund and this time she downright ghosted me; didn't even open my messages and when I demanded a reply she simply seenzoned me.
